FURNACE FOR CREMATING OR INCINERATING HUMAN BODIES.

SPECIFICATION forming part of Letters Patent No. 697,946, dated April15, 1902.

Application filed March 19, 1901. Serial No. 51,859. (No model.)

To all whom it may concern.-

Be it known that I, HENRY O. KUEHNE, residing at Middle Village, LongIsland, Queens county, New York, have invented certain new and usefulImprovements in Furnaces for Oremating or Incinerating Human Bodies, ofwhich the following is a specification.

My invention relates to a furnace for cremating or incinerating humanbodies, and has for its object to produce a furnace which will rapidlyincinerate bodies in an economical manner.

In the accompanying drawings 1 have shown in detail a cremating-furnacein which my invention is embodied. It will be understood, however, thatthese drawings are illustrative merely and that the construction may bevaried without departing from the spirit of my invention.

In the drawings, Figure 1 is alongitudinal sectional elevation of thefurnace. Fig. 2 is a section on line 2 2 of Fig. 1, which figure alsoshows the section-line 1 1, upon which the section Fig. 1 is taken; andFig. 3 is a sec tion in line 3 3 of Fig. 1.

In the drawings, 0, represents the side walls of the furnace, which arepreferably braced together by a frame or buckstay b.

0 represents a grate, and c" the combustionchamber, from which leads apassage or fiue (Z. This passage or flue cl leads into the body orcrematory-chamber e of the furnace.

Within the body of the furnace are two brick walls f, pierced laterallywith apertures g. Upon the Walls f a perforated fire-resisting plate orsupport 7b is placed. This plate or support receives the body to beincinerated. The passage cl leads under the support It. Leading from theupper portion of the crematory-chamber e, at the same end as the passaged, is a suitable due or stack 3'. This flue or stack j is preferablylocated in the front of the-furnace over the grate that is, said flueextends through the combustion-chamber c. It will be understood thatwhen the body has been placed upon the receiving-plate h the flame andhot gases pass from the fire-bed on the grate 0 through the flue (Z, andthus pass laterally through the apertures g and lap over upon the bodyplaced upon the plate It in the body of the furnace. The smoke andproducts of incineration pass forwardly and upwardly through the flue orstack j, in which they are subjected to a high degree of heat, inasmuchas the flue is exposed to the gases in the combustion-chamber c.

I find that a furnace constructed in the manner described will veryefficiently incinerate human bodies in a very thorough and rapid mannerand that by reason of the construction the incinerating flame and gasesare efficiently brought into contact with the body. Further, the gaseousproducts passing out through the flue j are effectively heated, so as todestroy any objectionable smell.

Having described my invention, what I claim, and desire to secure byLetters Patent,- 1s- 1. A crematingfu rnace, comprising astruc- I tureforming a crematory-chamber closed at one end, a combustion chamberlocated at the other end of the crematory-chamber, a support located inthe crematory-chamber at a distance above its bottom and spaced from thesides thereof, a passage leading from the combustion-chamber to thecrematory-cham ber below said support at the end of thecrematory-ohamber opposite to its closed end; and an outlet-flue leadingfrom the crematory-chamber above said support at the same end at whichthe said passage is located, whereby the combustion-gases will be causedto enter the crematory-chamber below the support, pass around thesubstance to be cremated, and back over the substance into the flue.

2. A cremating-furnace, comprising a structure forming acombustion-chamber and a crematory-chamber the inlet of whichcommunicates with the outlet of the combustionchamber, and anoutlet-flue leading from the Crematory-chamber through thecombustionchamber, said fiue leading directly from the crematory-chamberand having imperforate walls from the outlet of the crematory-chamher toa point beyond the combustion-chamber, so that the cremation productswill not pass through the combustion chamber on their way from thecrematory-chamber to the outlet-flue.

HENRY KUEI-INE.
